    • A linear cutting stapler comprises: an upper jaw and a lower jaw (5) capable of closing or opening relative to each other. A staple cartridge (51) is disposed at a distal end of the lower jaw (5). The lower jaw (5) is U-shaped, and has a staple driving rod (3) and a blade driving rod (4) slidably disposed therein. The linear cutting stapler further comprises a safety mechanism. The safety mechanism comprises an engagement member. A notch fitting the engagement member is disposed on a bottom surface of the staple driving rod (3). The safety mechanism further comprises a floating block (1). The floating block (1) may perform longitudinal displacement in the lower jaw (5). When the floating block (1) is pressed against the staple cartridge (51) or an anvil (6), a top end of the engagement member is driven to perform longitudinal displacement, so that the engagement member is separated from the notch. The linear cutting stapler has a simple structure, is easy to be fabricated, and is safe and reliable.
    • 线性切割订书机包括:能够相对于彼此闭合或打开的上钳口和下钳口(5)。 钉仓(51)设置在下钳口(5)的远端处。 下钳口(5)为U形,并具有钉驱动杆(3)和可滑动地设置在其中的刀片驱动杆(4)。 线性切割订书机还包括安全机构。 安全机构包括接合构件。 配合接合构件的切口设置在钉驱动杆(3)的底表面上。 安全机构还包括浮动块(1)。 浮动块(1)可以在下颚(5)中执行纵向位移。 当浮动块(1)被压靠在钉仓(51)或砧座(6)上时,驱动接合构件的顶端以执行纵向位移,使得接合构件与凹口分离。 线性切割订书机结构简单,易于制造,安全可靠。

    • The present invention provides an instrument for anorectal surgery, comprising a hollow main body, a suture junction disposed at a rear end of the main body and an inserting guider disposed at a front end of the main body. At an operating position, all or part of mucosa and tissues can get through the main body. At least one opening is made in the wall of the main body, and all or part of the mucosa and tissues can get into a hollow interior of the main body through the opening. Because of the openings on the wall of the main body, the present invention can be operated to perform the anorectal surgery of local and non-annular cutting, which facilitates a quick surgical operation, further allays the pain of the patients, and a better operation effect is obtained.
    • 本发明提供了一种肛门直肠手术器械,包括中空主体,设置在主体后端的缝线接头和设置在主体前端的插入引导件。 在一个操作的位置,全部或部分粘膜和组织可以穿过主体。 在主体的壁上形成至少一个开口,并且全部或部分粘膜和组织可以通过开口进入主体的中空内部。 由于主体壁上的开口,本发明可以被操作以进行局部和非环形切割的肛门直肠手术,这有助于快速的手术操作,进一步使患者的疼痛和更好的操作 效果得到。

    • A linear surgical stapler includes an upper staple cartridge receiving half-section, a lower staple cartridge receiving half-section and a staple cartridge assembly. The staple cartridge assembly includes a cutting groove in which a reciprocating movement cutter is mounted. The cutter includes a bottom surface and a knife blade located at a far end of the cutter. The staple cartridge assembly includes a restricting member mounted therein and an elastic stopper. The elastic stopper abuts against the restricting member when the staple cartridge assembly is in an initial state. The restricting member breaks away from the staple cartridge assembly when the staple cartridge assembly is in a firing complete state, thereby preventing the cutter from sliding towards the far end of the staple cartridge. As a result, misfiring throughout the whole operation of the linear surgical stapler is prevented.
    • 线性外科缝合器包括接收半部分的上部钉仓,下部钉仓接收半部分和钉仓组件。 钉仓组件包括其中安装有往复运动切割器的切割槽。 切割器包括位于切割器远端的底面和刀片。 钉仓组件包括安装在其中的限制构件和弹性塞子。 当钉仓组件处于初始状态时,弹性止动件抵靠限制构件。 当钉仓组件处于点火完成状态时,限制构件脱离钉仓组件,从而防止刀具朝向钉仓的远端滑动。 结果,可以防止线性外科缝合器整个操作过程中的点火不足。
